A great variety of potentially hazardous gases or vapors can be encountered in vehicle tunnels. They arise from three sources, namely vehicle exhausts; leaking fractured gas mains which may be carried in tunnels; and accidental spillage from tankers traveling through tunnels. No single gas-detection system is known that can cope with all the circumstances that might occur in a vehicle tunnel; the purpose of this article is to describe some of the new detection and monitoring techniques that have been developed at SMRE during the course of work aimed principally at monitoring the mine atmosphere. Among techniques discussed are: catalytic- polarographic- and semiconductor methods.
